LAMP-SHADE.

SPECIEICA1ION forming part of Letters Patent No. 323.624, dated August 4, 1885.

Application fiied Dccember S0, 1834. (No modal.) Patentd in France Jnly 16, 18:33, No. 156.553 in Beigium Febrnmy 18, 1834, No. 64,195, and in Germany Febrnary 15), 1884, No. 30,108.

T0 aZZ w7wm it may oncern:

Be it known that we, AUGUSTE BABA and ERNESIE DESJARDINS-LIEUX, citizens of the Repubiic of France, residing et Paris, in said Repnbiio, have invented certain new and usefn1 Improvements in Lamp-Shade Adjnsters, of WhiCh the following is a speeifioetion, reference being had therin to the accompanying drawings.

Figure]. is a central cross-section on line w a: 01' Fig. 2. Fig. 2 is 2L plan view of the dex ice.

The object of onr invention is to construet lamp-shades and reflectors so that they ean be easily moved on their ho1ders and thns cansed io refleot the light in any direction. This is done by a system of snperposed and concentric spherical surfaces and springe, ail as wii1 now be more fn1ly deseribed.

In the aeeompanying drawings, A is aspherical zone of any snitable materiai. The interna1 face of this zone is provided With c]asps or olaws B, which may be riveted to it or upon it, or otherwise held in place. In the annexed drawings they are shown fixed on springs 0, which are attaohed on the inside of the zone A. It is thisfirst piece,A,tha-t ismonnted on the chimney. Upon the external periphery of the zone A is placed another part,D,whioh is the shape of a conicni frnstum, and concen trie to the part A. so that it may be revolved free1y npon it. This part D may be composed of one or several pieces, as may be desired. Tho aocompanying drawings show the part D as made of two pieces joined together at their edges. It is on thesuperior tapered part that the shado E or refleetor is placed.

This shade is preferably made of two conica1 fruste nnited together at, their smaller ends.

If desired, the shade can be permanently seoured to the tapered part D.

The shade being monnted on the ehixnney by means of c1asps B, the operatf on of the device can be easily nnderstood. The sphericotapered piece D, upon whioh the reflector or shade is fixed, being independent of and concentric to the part A, can be readily moved upon the chimney so as 130 throw the light in any desired direction.

It is obvions chat, as the conicai part D is movable on the perDhery of the spherical zone A eoncentric With the axis of this zone, the shade E can be adjnsted at any desired angle within the limit of the breadth of this zone; hence the light can be refiected at different angles.

Having now desoribed our invention, we claim 1. The oombination of a spherieal zone, A, clasping-springs secnred inside thereof, and an adjustzble holder for a lamp-shade, substantiaiiy as described.

2. The combination of tbe sphericai zone A, springs B 0, the taPered shade-snpport D, adjnsta-hle on said zone, as desoribed.

In testimony whereof we aifix OUI signatures in presence of two witnesses.
